1.00 970301
     first version of commercial Simplot fixed for release of
     tab version 5.0

1.01 970511
     first version packed in gzipped tar file with installation
     instructions. Attempt to make everything installable with make 
     form the upper directory.

1.02
     Changed plget to allow for user testing if Simplot was initialized.

     Rearranged directories, improved Makefile.

     Added subroutine pllabels
     
     plformat now replaces "\n" sequences (resulting from user-input strings
     with real newlines before plotting the string
     
     added check for ascending x in plhiss

     changed the keywords FILL and BORDER to RECT_FILL and RECT_STROKE
     
     removed plotting of a border in plaxes. It's easier for the user to 
     plot that separately with plrectm, than to use plset(RECT_STROKE/
     RECT_FILL).

     made plmess plotting in the top center and centered to prevent 
     interference with y-axis labels
      
     970821:
     in P_p.c, incoming x- and y-values are now truncated right at the start
     because PostScript plots produced of /gc/714/fid gave problems in the
     highest peak. 

     970825: problems with large pen diameters and updating of plottings
     extremes. Corrected P_winupdate.c and P_p.c
     
     970906: changed P_p.c (and P_update.c) to accumulate PostScipt penmoves
     with pen down and dx=0. This is particularly useful for high-resolution
     spectral data. For example: the plot of NMR-spectrum 712/c reduced from
     765kB to 160kB
    
     971026: simplot.c now prints the version number to the log file

1.03
     981212: Converted from C to C++
     prepared for distribution
     msdos now out of order - use 1.02
1.04
     981221: corrected src/Makefile for missing lib-dependencies
     981221: plcolor produces wrong colors. Corrected
     981221: #-key didn't work in plformat; corrected 
1.05:
     990103: better makefile generation for manpages; 
     made installation independent of non-standard Perl modules and prv
     corrected error in temporary file creation in interpreter
1.06:
     more changes to the installation procedure
     added missing break in plevent.cc
1.07:
     corrected plrectr and plrectrm to use P_rect, as RECT_STROKE and RECT_FILL
     did not work.
     Xyplot now removes last characters in markers that generate color. If the marker becomes 
     empty, a colored dot will be plotted.
1.08:
     in plset/plget: removed _ from keywords RECT_FILL, RECT_STROKE, OPAQUE_TEXT
1.09:
     corrected plsmooth error message
     removed P_temp for temporary storage. Now done via malloc
2.0: converted documentation into html
     xyplot can do fourier transform
     added plfft
     added PRINT keyword to plset
2.1  Converted back from C++ to C
     Times-Roman (TR) did'nt work. Corrected
     inserted %%Page: comments in PostScript.
     plpage no resets everything like plinit
     !!> I now realised that having pages in the .ps file is illegal is we call it .eps.
     !!> There should then also be no %%Bounding Box. Have to look at this.
     corrected plsize: it did not handle "##" and other doubled specials well.
     Corrected xyplot: I forgot that after plpage now situation is back to that after plinit
2.2  corrected plformat, vsnprintf now conforming the C99 standard
     xyplot -p plotfilename now plots to plotfilename.eps
